FAQs

How much does AI real-time transcription cost?

We charge per second for AI transcription - for a more detailed breakdown please visit our dedicated pricing page.

How quickly will I get my transcription back?

You can start receiving transcription in under a few hundred milliseconds after the words are spoken through our partial transcription.

As more words are spoken, we use the context to correct ambiguous words until we give our final best transcription. These finals can be returned within 2 seconds, depending on the accuracy vs latency requirements.

How can you get real-time accuracy so close to the accuracy of transcribing a file?

At the core, the machine learning models we use are identical for batch file transcription and real-time.

This means that you get our best accuracy transcription in both modes. The small accuracy impact at lower latencies in real-time (<4s) comes due to having less context from the speaker.

How many speakers can be identified in real-time?

By default, we can identify up to 50 speakers in a real-time stream. This can be increased to 100 speakers.

What’s the longest stream time you support?

We can support streams over 24 hours long!

Stream duration is effectively unlimited - in fact we've had customers with streams running for over a month.

How many concurrent real-time connections can I have?

If you sign up through our portal you get two concurrent real-time connections on the free usage tier.

On our 'Pay As You Grow' tier you can use ten concurrent streams, and for our 'Enterprise' customers we support as many connections as you require.

Why we built our low-latency Text-to-Speech

Most TTS sounds great in demos but breaks in real conversations. We built ours for sub-150ms latency, natural voices, and global scale.
